Title: Process for preparing N,N,N',N'-tetra-acetylethylene diamine.
IPC: C07C231/00
Filed: 1979-04-06
Abstract: The invention provides an improved process for the manufacture of N,N,N',N'-tetraacetylethylenediamine by acetylation of N,N'-diacetylethylenediamine with acetic anhydride, by using these two starting components in a weight ratio of from 1:1 to 1:10, stopping the acetylation before attaining the reaction equilibrium between N,N'-diacetylethylenediamine and N,N,N',N'-tetraacetylethylenediamine, preferably after having attained a conversion rate of from 20 to 70 mol % of tetraacetylethylenediamine, relative to diacetylethylenediamine, purifying the reaction mixture in order to remove the dyeing impurities, and recycling to the acetylation the purified, incompletely reacted components. Purification may be carried out by vacuum distillation or by means of an adsorbent, for example bleaching earth or active charcoal. Optionally, from 0.01 to 0.3 part by weight of ketene per part by weight of diacetylethylenediamine are added to the starting components. The process may be carried out batchwise or continuously, and it gives a practically colorless product with high yield (more than 97%).

Title: Dry transfer system
IPC: B41M3/12
Filed: 1979-05-30
Abstract: A dry transfer system for transferring indicia to a receiving surface comprises a flexible but dimensionally stable carrier substrate with a film of cohesive, pliable and plastically deformable, indicium-forming material not more than 10 micrometers thick defining a preformed image and adhering to the front surface of the substrate. This surface is composed of a smooth material with adhesive properties such that without relying on adhesive the film can be released and transferred to a receiving surface in close contact, by a pressure transmitted through the substrate, but the film is retained on the carrier substrate in the absence of such pressure, in spite of close contact with the receiving surface.

Title: Injection piston for die casting
IPC: B22D17/32
Filed: 1979-07-17
Abstract: An injection piston for a die casting machine comprising, a piston die having a chamber therein open at one end, a die rod having an end slidable in the chamber for changing the volume thereof. A coolant is supplied to the chamber to act as a damper to the movement of the die rod toward the press die when the injection piston is moved under pressure into a mold. The coolant flows in a coolant path comprising a feed path defined in the die rod and a discharge path at least a portion of which is defined between the press die and the die rod and the rest of which is defined in the die rod. A slidably mounted immersion valve is in the end of the die rod adjacent the chamber and movable into a neutral, a first and a second position for selectively permitting the flow of coolant into and out of the chamber, blocking the flow of coolant altogether and permitting the flow of fluid only out of the chamber depending on the increase of pressure exerted on the injection piston as it is forced into a mold. A restraining member is biased toward the immersion valve for restraining its motion between its first and second operating positions.

Title: Apparatus and method for determining the consistency of a suspension.
IPC: G01N21/53
Filed: 1983-12-09
Abstract: In an apparatus and method for determining the percentage of solid particles in a suspension (consistency), diffused radiant energy is directed from a source (14) toward a suspension (11) to be measured. The portion of the energy which is forward-scattered by the suspension is detected (18) and a first signal indicative of the magnitude of the forward-scattered energy is produced. The portion of energy which is back-scattered by the suspension is detected (16) and a second signal indicative of the magnitude of back-scattered energy is produced. The first and second signals are combined (30) at a predetermined ratio to produce a feedback signal used to control the intensity of energy emitted from the radiant energy source (14). The intensity of energy emitted from the source (14) is a function of the forward-scattered and back-scattered energy and is directly proportional to the consistency of the suspension (11) being measured. By monitoring the power driving the radiant energy source, a display calibrated in terms of percent consistency can be provided.
